HUB-WRENCH.

SPECIFICATION forming part of Letters Patent No. 636,456, dated November 7, 1899.

Application filed July S, 1899. Serial No. 723,223. (No model.)

T0 all whom t may concern.:

Be it known that we, HENRY SAULs and GEORGE S. OOOK,citizens ofthe United States, residing at Mineral, in the county of Bee and State of Texas, have invented a new and useful Hub-Wrench, of which the following is a speciiication.

This invention relates to hub-wrenches, and has for its object to provide an improved support which is adapted to be fitted to the hub of a Wheel and also a wrench proper, which is adapted to be turned axially upon the support, so as to unscrew the hub-attaching nut from the axle-spindle, whereby said hubattaching nut may be removed without turning or otherwise changing the relatively-iixed position of the wheel upon the axle.

A further object is to provide the wrench proper with a longitudinally-slidable adjustment upon the support, so that after being unscrewed from the axle-spindle the hub-attaching nut may be quickly withdrawn away from the end of the spindle, thereby facilitating the lubricating of the latter.

To these endsthe present invention consists in the combination and arrangement of parts, as willbe hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood thatv changes in the form, proportion, size, and the minor details of construction may be made within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the present invention. V

In the drawings, Figure l is a perspective view of the device. Fig. 2 is a longitudinal sectional view thereof applied to the hub of awheel. v

Corresponding parts in both figures of the` drawings are designated by like characters of reference.

Referring to the accompanying drawings, l designates a iiat circular band having a yoke-shaped brace 2 extending entirely at one side of the plane of the band and connected thereto at diametrically opposite points, and the band is further provided with a plurality of radially-disposed set-screws 3, passing through threaded openings provided in the band and having their heads located exteriorly thereof in convenient position for operation. l

Located centrally within the band and extending at right angles to the plane thereof are the clamping-jaws 4, which are carried by an adjusting-stem 5, supported by the yokeshaped brace 2. The adjusting-stem is provided at its outer end with an operating-crank 6,'and said stem is adapted to slide loosely through a circular opening 1l, formed in the yoke 2, and is circular in cross-section, so as to turn axially, fora purpose as will be hereinafter more fully explained.v The jaws 4 are formed from a single length of spring metal bent intermediate its ends into substantially U shape and are flxedly connected to the inner end of the adjusting-stem at the bend of the jaws. The inner sides of the jaws, at the free ends thereof, are provided with notches 7, adapted to embrace the corners of the nut, and a thumb-screw 8 connects the jaws, whereby the latter may be clamped upon the nut. As best shown in Fig. 2, it will be seen that the stem 5 is reduced, as at 12, near its inner end, whereby an annular shoulder 13 is formed. The base of the jaws 4 is provided with an opening adapted to receive the reduced portion l2 of the stem 5 and is clamped against the annular shoulder 13 by means of a suitable nut 14, fitted to the threaded inner extremity of the stem. The reduced portion 12 of the stem 5 andthe opening in the base of the jaws 4 are both angular in shape, so as to prevent axial movement ofthe jaws upon the stem.

In the application of the device as shown in Fig. 2 of the drawings the circular band 1 is adapted to embrace the outer hub-band 9, and the set-screws 3 are set against the hub` band, so as to connect the device firmly therewith, 'after which the jaws 4 are adj usted longitudinally by means of the stem 5, so as to engage the hub-attaching nut 10, and then the thumb-screw 8 is operated to clamp the jaws firmly to said nut. When the device has thus been rmly connected to the hub and engaged with the hub-attaching nut, the crank 6 is operated to turn the stem and likewise the jaws 4, whereby the latter are adapted to unscrew the nut from the end of the spindle. As the stem 5 is slidably mounted through the opening in the yoke-shaped brace IOO 2, the jaws of the wrench and also the nut may be quickly withdrawn from the end of the spindle, so as to expose the latter for convenient lubrication.

From the foregoing description it will be understood that the wheel remains in its relatively-lixed position upon the axle-spindle and is not turned thereon. After the axle has been lubricated the slidable stem and the wrench-jaws may be pushed longitudinally inward, so as to quickly engage the hub-attaching nut with the end of the spindle, after which the crank is turned to screw the nutin position. Thus it will be seen that the wrench is carried by the support and the nut remains within the jaws of the wrench, so that it is not necessary to soil the hands in the operation of the present device.

I'Ieretofore hub-wrenches have been provided with a support which is adapted to be itted to the hub, and also wrench-jaws; but the latter have had a screw-threaded shank tted in a screw-threaded opening in the support, so that after the nut has been disengaged from the axle it is still necessary to turn the stem in order to draw the nut away from the end of the spindle. This operation is exceedingly slow and awkward, and in view of this diiiculty we have provided improved means whereby the nut may be quickly drawn away from the end of the spindle after having been detached from the threads thereof.

Vhat we claim isl. A hub-wrench, comprising` a support adapted to be fitted to the hub of a wheel, a brace carried by the support and projecting at one side thereof, and a wrench proper located between the support and the brace, and having an operating-stem slidable longitudinally upon the brace, and also having an axial movement thereon, substantially as and for the purpose set forth.

2. A hub-wrench, comprisingaband adapted to be fitted to the hub of a wheel, an arched or yoke-shaped brace carried by the band and projecting at one side only thereof, clampingjaws located within the band, and a cross-sectionally round stem carrying the jaws at the inner end thereof, slidable longitudinally through the arched or yoke-shaped brace, having an axial movement thereon, and provided at its outer end with an operating-handle, substantially as and for the purpose set forth.

3. In a hub-wrench, the combination with a band having radial set-screws adapted to connect the band to the hub of a wheel, and an arched or yoke-shaped brace connected at diametrically opposite sides of the band and projecting entirely at one side of the plane thereof, of clamping-jaws formed from a single length of spring metal bent intermediate of its ends to provide jaws, a thumb-screw adjustably connecting the free ends of the jaws, and an adjusting-stem xedly connected at its inner end to the bend between the clamping-jaws, slidable longitudinally through the arched or yoke-shaped brace, having an axial movement thereon, and provided at its outer end with an operating-handle, substantially as and for the purpose set forth.

In testimony that we olai 1n the foregoing as our own we have hereto aiiXed our signatures in the presence of two witnesses.
